Sakura Incubator

Getting to it

The incubator sits in the Cherry Blossom biome, which is gated behind 2.5B Speed and the requirement to feed a crane to the cherry blossom tree to open the region. Check both conditions before travelling — see the Cherry Blossom guide for the full route.

The recorded Sakura Crystal source

The machine runs on Sakura Crystals, and the linked sources describe obtaining crystals during the Great Bloom. You smash blooming Sakura trees with your bat during a window that opens every 30 minutes and stays open for about 3 minutes. That works out to roughly 10% of a repeating hour under that schedule. The timer needs to be aligned to an event you observe; this percentage does not establish a global server start time.

The odds, and what they actually mean

Using the reported probabilities, the probability-weighted multiplier in the floor case is 1.537× the base income. This is a model average across outcomes, not a multiplier that a single egg receives or a guarantee within 40 attempts. The corresponding reported ceiling scenario gives 2.10×, because the tail is now 40% of outcomes. These calculations assume the two listed outcomes cover the roll and their factors apply to the same unmodified base. They exclude crystal and Robux costs, unknown egg contents and any interaction with existing mutations.

Read the odds and cost as you charge

An egg placed in the incubator can be charged, and the charge percentage is displayed on the machine along with the odds it currently gives. The ceiling is 150%. Charge climbs as you feed the machine, and the Spirit Bloom share climbs with it — a walkthrough shows the reading at 26%, at 100%, and finally at 150%, with the odds moving each time.

Charging consumes crystals, so a higher success probability does not make it costless or automatically optimal. Record the extra crystals required and the change in the displayed probability before deciding whether to keep charging. The cited recording supports a higher probability at full charge; it does not establish a complete cost-per-success comparison.

The paid Luck Boosts

Three Luck Boosts can be bought with Robux and they stack, reported at 16, 32 and 64 Robux. With all three applied on top of a 150% charge, the Spirit Bloom rate is reported at 40% — the figure two independent sources agree on. Nobody has published the curve in between, so we give the two ends and not a table of steps we would be inventing.

A higher chance still permits a Bloom result. Check the current purchase price and displayed odds before any paid choice; the prices above are those reported by the linked sources. 40% is a rate, not a promise, and six in ten rolls still miss at the ceiling.

Which eggs deserve a crystal

The table illustrates a conditional calculation using listed base incomes. It assumes the factor applies to that base, with the same size and no existing mutation. It does not prove that an unopened egg will produce a particular species:

A Spirit Bloom on a Chicken adds $2 per second. The same roll on Kitsune adds $3.6B per second. At equal costs and probabilities, a known higher base gives a larger modeled gain. For an unknown hatch outcome or an egg already carrying a mutation, that comparison needs more information. The income calculator lets you compare your own specific cases.

What we still do not know

Until 7 September 2026 this page said that nothing was known to influence the incubator roll. That was wrong, and the two sections above are the correction: charge moves the odds and the paid Luck Boosts move them further. What remains genuinely open is the shape of the curve between the two ends. We have the floor at 2.5% and a reported ceiling of 40%, plus a single reading of roughly 5% at full charge before any boost — one recording, one reading, so not enough to publish a table.

Also open: whether anything outside the machine moves it, such as event boosts or a luck stat. Nothing we would trust documents that either way. If you have charged a run of eggs and written down the odds the machine showed at each step, that is exactly the data that would close this — and it would be credited to you.

Sakura Incubator FAQ

What does the Sakura Incubator do?

It applies the Bloom or Spirit Bloom mutation to an egg, multiplying the income of whatever hatches from it by 1.5x or 3x respectively.

What are the Sakura Incubator odds?

They are a range, not a fixed pair. An uncharged egg with no paid boost rolls Spirit Bloom on 2.5% of attempts — about one in 40 — and Bloom the rest of the time. Charging the egg raises the Spirit Bloom share, and all three Luck Boosts raise it to a reported 40% at full 150% charge.

Should you charge the egg before mutating it?

Charging uses crystals and can raise the displayed odds. Whether to spend more crystals depends on their cost and your alternatives. The recorded uncharged case is near the 2.5% floor; a recording shows a higher rate at full charge before paid boosts. Check the machine’s current reading.

Where is the Sakura Incubator?

In the Cherry Blossom biome, which needs 2.5B Speed and a Crane fed to the Cherry Blossom Tree to open.

How do you get Sakura Crystals?

By smashing blooming Sakura trees with your bat during the Great Bloom event, which opens every 30 minutes and lasts about 3 minutes.

Which eggs should I use crystals on?

If the target income is known and costs and odds are comparable, the same multiplier adds more to a higher base. For an unidentified outcome, account for hatch uncertainty and existing bonuses rather than assuming the biome maximum.
